Amazon Linux 2 : curl (ALAS-2022-1808)

high Nessus Plugin ID 163226

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of curl installed on the remote host is prior to 7.79.1-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1808 advisory.

 - libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily. (CVE-2022-27782)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update curl' to update your system.
